A friend that has been through a patent dispute tell me filing for a patent is just an invitation to spend a half-million in Federal court. He just keeps trade secrets now and moves faster than his competition.
Here's the pseudo-code for patent
infringement transactions for semi industry.
If(Somebody sue you)
publicly deny infringement;
If (you have similar patents)
Counter sue the guy;
Buy similar patents from Trolls
And counter sue the guy;
Wait (until the guy turn up for negotiations)
Settle out of court. & kickout the lawyers.
Hug each other & do cross licensing deal
If(person suing=(university+ a crazy jury ard)
throw and few $$ for univ research grant
run for life;
get ready with 1.2B$ for 2 silly patents.
